The more themes you incorporate, the more creative you will have to be but the process is basically the same. It will also depend how similar or different the themes are. Combining some themes like an Asian theme and Zen theme would be easier than a Zen theme with a rock-star theme. The primary task here is to identify the common factor in the living room ideas. For instance, in combing an Asian and Zen theme, you would incorporate a more natural Asian representation like bamboo, jade and the concept of feng shui. You could also incorporate meditation cushions that would be used in Zen lifestyle and simultaneously represents a classic Asian seating arrangement.

Select individual pieces that you love and that show off your style rather than groupings, or in sets.

Consult your color wheel to choose an appropriate color scheme. Keep the colors in the same family unless your theme is rainbow. Sometimes contrast looks awesome. For instance a brightly colored, woven bohemian blanket would pop nicely against a modern, stark white couch.
